(cuss-i) Claims.

The invention relates to connectingi'pinsoi the type commonly used to pivotallyi connect 'brake levers, brake connecting rods and similar parts 01 e b ake rigging oi a 'rentional connecting pin headed portion at one end andj being provided adjacent itsopposite end with a transverse bore adapted to receive a cotter pin, saidheaded porbeing adapted to prevent or limit the longitudi e necting pin after assernbly. For the purpose of illustrati g one of the uses of awconnecting pin 1 show, in heaccompanying drawing, -a. portion of a connection rod having a bifurcated end porfreight can The con} used for this purpose comprises a round elongated metal pin having a in movement of the con- 1942.; Application s 151 485, I e

portion of a brake lever, portion of a connectiing rod, and the connectingpinhi myinven' tion pivotally securing. the lever androd. Figgz is ,a perspective view of the two parts" of my connectingpin, Fig. 3 isasidef' the connecting pin, onejof the parts being "in assembled position in the. aligned apertures oi the brake lever. and connecting rod jaws, the other part'being showi'i'iir starting position, the

brake leverl andconneeting' rodjaws being shown insection. v H Fig. 4 is aview similar tofFig; 3, showing both parts of the "connectingfpinin assembly with tion p votally connected to theend portion. of a hrakejlever. The method of connecting, such a rod and: lever, with the 'eonvention al connecting pin,- is --to insert the connecting pin throughgthe aligned apertures in the furcations and the apertur i t d headed portion of the connecting pin is in abut; ting engagement with the outer face; of one of the furcations, the opposed end of ,the pin ex tending outwardly and bey ond .the"outer face ftheo th r furcation. A cotter pinis .then. in serted'through the bore in the (exposed end of the connecting pin and spread in the usual way.

One of the seriousobjections' to the use foi a cotter pin, forholding -the connecting. pin in as: 0 that the cotter pin has small .Aiurther object is to'pmvide a: novel,' two piece connecting pin which, after assembly". with .the brake. rigging, will provide a, rugged headed portion at both ends .of. the .pin, these headed portions having ample and equal resistance to wear againstthe members withjwhich'the pin is as i d j A furtherobject is I otallyconnecting devices wherein the means for holding the;pin against. longitudinal,,displace .tnentwiilbe an integral-part of the pin and of the brake lever until the members'with which it is headed pmonzz of-each of the members Wand with respect 'to the Shani;
